Fix quicksearch UI/UX
We have an inconsistent experience with regards to quick searching a table. On the topics table the quicksearch field is embedded into the table header whereas other tables such as consumer groups have an external, more present quicksearch field. We've got various user reports that they could not find the search field in the topics table anymore as it was too hidden (especially on larger displays) within the table header.
